Description
Technical field
The present invention relates to and belongs to hydraulic press manufacturing technology field, and particularly a kind of hydraulic press is used the bolt-type safety device.
Background technology
When repair apparatus or correction mould, need the operator to get into the press internal work usually, the potential safety hazard that this just exists press slide to fall and bring, general device also are provided with mechanical safety cock except that the support of hydraulic system.At present, the form of safety cock has rotary, collapsible.The safety cock of above-mentioned form is generally through complicated electric elements or Hydraulic Elements control, and structure is complicated, receives the restriction in space when mounted; Simultaneous faults point is more; Be the pipeline complex connection, be prone to phenomenons such as leakage of oil, and improved maintenance cost.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to install and also take up room little, for ease of maintenaince, hydraulic press that security performance is high uses the bolt-type safety device.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of hydraulic press is used the bolt-type safety device, it is characterized in that: this safety device mainly comprises support, cover plate, safety cock and cylinder, and wherein said support is packed on the sidewall of hydraulic machine column; Said cover plate is packed in the outside of support, and cover plate and support form a rectangular channel, and pinboard is installed in the said rectangular channel; Pinboard connects the piston rod of cylinder, and cylinder installs on the cover board, and the end of said pinboard is provided with installing hole; Install safety cock in the installing hole; Be set with support spring on the said safety cock, following the sitting up straight of support spring is contained on the pinboard, and safety cock is provided with spacing ring; Be provided with guider between pinboard in the said rectangular channel and the rectangular channel inwall.
The present invention can also adopt following technical measures:
Said guider comprises bolt shaft, and said bolt shaft is installed spiral shell and is contained on the support, and guide bearing is installed on the bolt shaft.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, make the present invention and traditional rotary and collapsible having the following advantages:
1, safety cock adopts the bolt-type structure, rectilinear motion, and simple in structure, requisite space is little, can not look like rotary safe bolt in the past, limited by installing space;
2, safety cock adopts the bolt-type structure, and processing is simple, convenient installation and operation.
3, safety cock adopts cylinder to promote, and cylinder carries travel switch, and electrical control is simple to operate; Pipeline connects simple, does not have oil leakage phenomenon, cleanliness without any pollution;
4, the safety cock pinboard is led by bearing, and rolling friction, push-and-pull resistance are little; And bearing is fixed by the shaft type screw, and guide frame is simple.

Fig. 3 is the guider structural representation.
Among the figure: 1, support; 2, cover plate; 3, safety cock; 3-1, spacing ring; 4, hydraulic machine column; 5, pinboard; 5-1, installing hole; 6, cylinder; 7, support spring; 8, guider; 8-1, bolt shaft; 8-2, guide bearing.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 to Fig. 3, a kind of hydraulic press is used the bolt-type safety device, and this safety device mainly comprises support 1, cover plate 2, safety cock 3 and promotes the cylinder 6 that safety cock moves horizontally; Wherein said support 2 is packed in through securing member on the sidewall of hydraulic machine column 4, and said cover plate 2 is packed in the outside of support 1, and cover plate 2 forms a rectangular channel with support 1; Pinboard 5 is installed in the said rectangular channel; Pinboard 5 connects the piston rod of cylinder 6, and cylinder 6 is packed on the cover plate 2, and the end of said pinboard 5 is provided with installing hole 5-1; Install safety cock 3 in the installing hole 5-1; Be set with support spring 7 on the said safety cock 3, following the sitting up straight of support spring 7 is contained on the pinboard 5, and safety cock 3 is provided with spacing ring 3-1; Be provided with guider 8 between pinboard 5 in the said rectangular channel and the rectangular channel inwall, said guider 8 comprises bolt shaft 8-1, and said bolt shaft 8-1 installs spiral shell and is contained on the support 1, and guide bearing 8-2 is installed on the bolt shaft 8-1.
Operation principle of the present invention, when hydraulic press needed repairing or repair a die, cylinder 6 ejected, and safety cock 3 advances, and gets in the working region, as the safety device of preventing that limited slip block falls; When hydraulic pressure confidential work, cylinder 6 is return, safety cock 3 zone of deactivating.
Because the present invention adopts technique scheme, make the present invention and traditional rotary and collapsible having the following advantages:
1, safety cock adopts the bolt-type structure, rectilinear motion, and simple in structure, requisite space is little, can not look like rotary safe bolt in the past, limited by installing space;
2, safety cock adopts the bolt-type structure, and processing is simple, convenient installation and operation.
3, safety cock adopts cylinder to promote, and cylinder carries travel switch, and electrical control is simple to operate; Pipeline connects simple, does not have oil leakage phenomenon, cleanliness without any pollution;
4, the safety cock pinboard is led by bearing, and rolling friction, push-and-pull resistance are little; And bearing is by the shaft type bolt, and guide frame is simple.
